STERILIZATION OF HYBRID MARMOSET (CALLITHRIX SP.) FEMALES: AN EVALUATION OF TWO SURGICAL METHODS

Abstract Population control techniques, either permanent or reversible, are important tools for the management of wildlife in captive and natural environments. Among these, surgical sterilization provides a permanent solution to unwanted reproduction. Surgical techniques can differ in their invasiveness and in the subsequent effect on behavior and physiology. For social animals, techniques that preserve gonads, such as vasectomy for males and ligation of uterine tubes for females, may be preferred because they maintain important physiology that influences behavior. This study compared two sterilization procedures for captive hybrid marmosets (Callithrix sp.). Twenty adult females undergoing tubal ligation were divided into two groups and received treatment either with a laparotomy or a laparoscopic method. The following parameters were evaluated for each female: duration of procedure, pain levels, weight gain, wound healing, adhesion, and inflammation. The results indicate that both techniques were equall...
